Ryōhei Mori


Ryōhei Mori is a Japanese scientist, inventor, and entrepreneur. He is the CEO of Green Science Alliance Co., Ltd. and Fuji Pigment Co., Ltd., and serves as President of Quantum Materials Technology and e-Gle Tech Co., Ltd. Mori is known for his work in eco-friendly green technologies, including aluminium-based rechargeable batteries, recycled lithium-ion batteries derived from black mass, carbon dioxide conversion methods, quantum dots, metal–organic frameworks, deep eutectic solvents, solid acid catalysts, and petroleum-free biodegradable plastics and plant biomass-based materials.

Education

Mori earned his undergraduate degree in Applied Biology from Kyoto Institute of Technology in 1997. He received his M.Sc. and Ph.D. in engineering from Kyoto University. In 2021, he completed the General Management Program at Harvard Business School.

Career

Mori joined Fuji Pigment Co., Ltd., where he later became CEO. In 2010, he established Green Science Alliance Co., Ltd. He has developed and commercialized rechargeable aluminium-based battery systems designed for safer and more sustainable energy storage, including aqueous aluminium-ion batteries and recycled lithium-ion batteries produced from black mass.
He is also known for creating fully biodegradable plastics and a wide range of bio-based materials derived from natural plant biomass without using petroleum-based components.
In 2023, his work on plant- and biomass-based biochemical materials was featured on the cover of RSC Sustainability.
In 2025, his work on aqueous aluminium-ion batteries was featured on the cover of Energy Advances.
Green Science Alliance Co., Ltd. has been supported by United Nations organizations. The company was selected as a green technology startup under the UNOPS Global Innovation Centre Japan incubation programme in 2020, with its green technologies registered under WIPO GREEN. In 2025, the company received grant funding from UNIDO for a green industrial recovery project in Ukraine.

Research focus

Mori’s research focuses on sustainable technologies in energy and materials science. His work includes rechargeable aluminium-based batteries, recycled lithium-ion batteries from black mass, and carbon dioxide conversion technologies.
He has also developed biodegradable polymers and chemicals derived from natural biomass to replace petroleum-based plastics.
Mori has researched quantum dots produced from waste materials including organic biomass, plastics, food waste, and municipal solid waste, with applications in fertilizers, antimicrobial materials, pesticides, and insect repellents. His work also covers metal–organic frameworks, deep eutectic solvents, solid acid catalysts, platinum-free fuel cells, perovskite solar cells, and organic thin-film solar cells.
